GROUND WATER LEVEL ADJUSTING LOCK
PROBLEM TO BE SOLVED: To easily and surely adjust a water level while suppressing an increase in the cost.SOLUTION: A ground water level adjusting lock 40 includes: an external cylinder 41 having an introduction port 44 connected to a culvert pipe 13 buried in the ground and a drain port 45 connected to a drain pipe 14 on a bottom portion thereof, and upwardly extended from the bottom portion; an internal cylinder 42 provided in the external cylinder 41, having a lower end connected to the drain port 45, and having a plurality of through holes 46 formed in a vertical direction; and a closing cover 43 attached to an outer peripheral surface of the internal cylinder 42 and capable of closing the through holes 46 in accordance with an attachment position in the vertical direction with respect to the internal cylinder 42. The closing cover 43 can be switched between a state of being elastically deformable in a radial direction of the internal cylinder 42 to the outer peripheral surface of the internal cylinder 42 and closing the through holes 46 by being firmly attached to the outer peripheral surface of the internal cylinder 42 and a state of being elastically deformed from the outer peripheral surface of the internal cylinder 42 to the radial direction outer peripheral side and slidably movable in the vertical direction along the internal cylinder 42.
【課題】コスト増を抑えつつ、水位調整を容易かつ確実に行う。【解決手段】地下水位調整水閘40は、地中に埋設された暗渠管13に接続される導入口44及び排水管14に接続される排水口45を底部に備え、底部から上方に向けて延びる外筒41と、外筒41内に設けられ、下端が排水口45に接続され、上下方向に複数の貫通孔46が形成された内筒42と、内筒42の外周面に装着され、内筒42に対する上下方向の装着位置に応じて複数の貫通孔46を閉塞可能な閉塞カバー43と、を備える。閉塞カバー43は、内筒42の外周面に対し、内筒42の径方向に弾性変形可能であり、内筒42の外周面に密着して貫通孔46を閉塞する状態と、内筒42の外周面から径方向外周側に弾性変形し、内筒42に沿って上下方向にスライド移動可能な状態との間で切り替え可能とされる。【選択図】図1
